The sum of two number a and b is
Its square is
Half of c is
And we have to subtract this from what we got before:
Finally, we multiply everything by 5:
4x² + 2x - 30 = 0
<span>
factor out the GCF:
</span>2(2x² + x - 15) = 0
<span>
factor the trinomial completely:
2x</span>² + x - 15 = 0
2x² + 6x - 5x - 15 = 0
2x(x + 3) - 5(x + 3) = 0
(2x - 5)(x + 3) = 0
<span>use the zero product property and set each factor equal to zero and solve:
2x - 5 = 0 or x + 3 = 0
2x = 5 x = -3
x = 2.5
</span><span>The roots of the function are x=-3, x=2.5</span>
Answer:
$41.73
Step-by-step explanation:
65x.40=26
65-26=39
39x.07=2.73
39+2.73=41.73
Answer: 8.75 Miles
Explanation: In this scenario, you want to add 2.2 to 6.55 to get the initial elevation, and by completing the equation 6.55 + 2.2, you would get your answer of 8.75
You would multiply 6 x 6 for tge pear to get 36 then multiply that by 3 dollars and get your answer and for the apples u multiply 1 with 8 to 8 dollars and see which one is cheap and that is the better one
